Description
Running reanalyze https://github.com/rescript-association/reanalyze/commit/389dd682223201b42c33e5c444e5c79e0805adad on Goblint https://github.com/goblint/analyzer/commit/a544002114324a207df72f9e79eb656c3ebe7b5b revealed the following.
In a file we have this binding operator definition:
let (let+) xs f = List.map f xs
This is marked dead even though the operator is used later in the file. I'm guessing reanalyze just doesn't handle this newer syntactic structure.

Research direction
Start by reproducing reanalyze on the linked ReScript reanalyze and Goblint commits, then trace the dead-value analysis for the OCaml binding operator let+. Done means a binding operator used later in the file is no longer reported as dead.
